Low-profile basin installed with a built-in drain

ABSTRACT

A low-profile shower basin ( 2 ) is installed with a built-in drain. The low-profile drain built into the basin allows the height ( 6 ) of the basin to be reduced as much as possible, approximately to between 5 and 10 cm depending on the material of construction.

This invention is an extra-flat shower pan (2) that is to be installed with a drain integrated into its body. This extra-flat drain that is integrated into the body of the pan enables the latter to have the possibility of having the lowest possible height (6) for obtaining a height of about 5 to 10 cm according to the manufacturing material of the pan.

In the field of bathrooms, there are generally two types of pans. The first type of pan (2) is an extra-flat pan (FIG. 1) with a separate drain that is embedded in the floor (4); this type of pan is manufactured with an edge height (6) of about 5 to 10 cm, therefore not very high such that access is more convenient. The difficulty for installation of this type of pan is the height of the siphon (1) (3) of the drain that is to be screwed into the pan and buried in the depth of the floor (5), hence the necessity for major masonry work, which has to be done by a professional.

The second type of pan that exists is a raised pan that is to be installed (FIG. 2). As can be noted, this pan requires a certain height (6) (FIG. 3) in order to absorb the drain volume (1) (3). It is very simple to install in the bathroom, without major masonry work, but due to its height (6), it is less aesthetic and has less convenient access.

This invention relates to an extra-flat pan to be installed (2) without masonry work (FIG. 4) and equipped with an extra-flat drain that is integrated into the body, whose drain shape (FIG. 5) (14) could be molded at the same time and directly in the body of the extra-flat pan with the same manufacturing material of the pan. This innovation makes it possible that this pan be equipped with a drain that is integrated into the body to obtain the lowest height (6) possible. This drain is equipped with barriers (9) that make it possible to create the water guard in the space (8) and using the part (10) creates the shape of the siphon and drains via the drain pipe (1). This drain makes it possible to preserve a height that is necessary for the water guard in the space (8) and because of the two slopes (7), the latter make it possible to reduce the storage of waste water accessible to the open air.

The shape of this drain (14) could be very easily integrated into the mold of a ceramic pan, in the mold of a plastic pan, and in the mold of a metal pan. And once the pan is manufactured, the imprint of the shape of the drain is integrated into the body of the pan (2).

In this way, we no longer need to provide a drain and to adapt it to the pan because the pan has its own drain that is equipped with a siphon and a water guard for preventing bad odors. Inside this drain, it is necessary to have slopes (7) located in the space (14) for, on the one hand, limiting the amount of stored waste water that is accessible to the open air in the space part (8) that is limited between the barriers (9) and the height (15) (between ⅛ and ¾ of a liter of water), and, on the other hand, to accelerate the flow of waste water (11) to the pipe (1).

In the drain part of this extra-flat pan (2), the piece (10) comprises a cover (13) that allows access into the siphon that is integrated with the form (14) if obstruction and the grid (12) hide the unit from the drain by limiting the travel of non-liquid materials that could prevent the draining of the liquids (11).

The height (6) of the extra-flat pan can be calculated according to the following rule: this depends on the thickness of the raw material with which the pan is manufactured (ceramic, plastic, or metal . . . ), the width and the length of the part (14) of the angle and the depth of drainage (16), the height of the barriers (9), the travel distance between the piece (10) and the barrier (9), the depth of the space of the water guard (8), and the height (15) that specifies the end of the slope (7). The height of the barrier (9) shows the height of the water guard.

The function of drainage, taking into account the height of the water guard, could be built into an extra-flat pan that is to be installed in the following way, by way of example:

For a plastic pan that is manufactured by heat-forming for a dimension: width 90 cm, length 90 cm for a height (6) of 7 cm, the maximum drainage depth (16) up to the drain is 15 mm. The depth (8) from the beginning of the slope (7) is 5 cm. The space for the passage of water between the piece (10) and the depth (8) is 15 mm, and the space for the passage between the piece (10) and the barrier (9) is 1 cm. The height of the barrier (9) is 40 mm. The height (15) could be equal to or slightly less than 5 mm maximum than the height of the barrier (9); this would limit the amount of waste water that is stored in the water guard and that is accessible to the open air.

Consequently, if we keep within the dimensions that we just indicated, we can obtain an extra-flat pan with a height of 7 cm.
